Library to work with NB-Not (Narrow Band Internet of Things) module SIM7020 with built-in support network Protocol MQTT (message queuing telemetry transport). This Library is a tool for working with AT commands and can be easily converted to work with other modules of the SIMCOM family.
| Node | Description |
|---|---|
| ascii-to-hex | Converts a string by changing the characters it contains from ASCII format to Hexadecimal format. |
| example-get-hardware-info | Example to verify the SIM7020 device.
|
| example-gsm-check | Example to check the network registration. |
| example-publish-to-mqtt | Example to publish the pot value to the Adafruit.io web service using the MQTT Protocol. |
| example-send-sms | No description |
| example-temp-logger | Example of a simple temperature logger. |
| generate-random-client-id | Generates a random CAP-sized clientID string of Latin characters from "a" to "z". |
| search-for-sequence | Check the string for a specific character sequence. |
| send-cmd | Sends an AT command to sim7020 module. |
| sim7020-exe-at | Sends "AT" execution command to SIM7020 module.
"AT" command is basic and is used to make sure the module is enabled and the UART interface is functioning. |
| sim7020-exe-atz | Sends "ATZ" execution command to SIM7020 module.
"ATZ" command resets default module configuration. |
| sim7020-exe-ccid | Sends "AT+CCID" execution command to SIM7020 module.
"AT+CCID" command shows ICCID data of the device.
ICCID is a unique serial number that a SIM card contains. |
| sim7020-exe-cgcontrdp | Sends "AT+CGCONTRDP" execution command to SIM7020 module.
"AT+CGCONTRDP" command reports current PDP parameters such as APN (Access Point Name), local IP address, subnet mask e.t.c |
| sim7020-exe-csq | Sends "AT+CSQ" execution command to SIM7020 module.
"AT+CSQ" command returns received signal strength indication RSSI and
channel bit error rate BER from the ME.
|
| sim7020-exe-gmi | Sends "AT+GMI" execution command to SIM7020 module.
"AT+GMI" command reports one or more lines of information text which permit the user to identify the sim7020 device manufacturer. |
| sim7020-exe-gmm | Sends "AT+GMM" execution command to SIM7020 module.
"AT+GMM" command reports one or more lines of information text which permit the user to identify the specific model of sim7020 device. |
| sim7020-exe-gsn | Sends "AT+GSN" execution command to SIM7020 module.
"AT+GSN" command reports the IMEI (international mobile equipment identifier) number in information text which permit the user to identify the individual sim7020 device. |
| sim7020-read-cgact | Sends "AT+CGACT?" read command to SIM7020 module.
"AT+CGACT?" command indicates the state of PDP (Packet Data Protocol) context activation. |
| sim7020-read-cmqnew | Sends "AT+CMQNEW?" read command to SIM7020 module.
"AT+CMQNEW?" command shows all connected MQTT instances. |
| sim7020-read-cops | Sends "AT+COPS?" read command to SIM7020 module.
"AT+COPS?" command returns the current mode and the currently selected GSM operator. If no
operator is selected, FRMT and OPER fields are omitted. |
| sim7020-read-cpin | Sends "AT+CPIN?" read command to SIM7020 module.
"AT+CPIN" command returns the SIM card state and an alphanumeric string indicating whether some password is required for the SIM card or not. |
| sim7020-read-creg | Sends "AT+CREG?" read command to SIM7020 module.
"AT+CREG?" command returns the status of result code presentation N and the value integer STATE which shows whether the network has currently indicated the registration of the device. |
| sim7020-write-cmqcon | Sends "AT+CMQCON=" write command to the SIM7020 module.
"AT+CMQCON=" command sends MQTT connection packet. |
| sim7020-write-cmqdiscon | Sends "AT+CMQDISCON=" write command to SIM7020 module.
"AT+CMQDISCON=" command disconnects MQTT. |
| sim7020-write-cmqnew | Sends "AT+CMQNEW=" write command to SIM7020 module.
"AT+CMQNEW=" command creates new MQTT instance. |
| sim7020-write-cmqpub | Sends "AT+CMQPUB=" write command to SIM7020 module.
"AT+CMQNEW=" command sends MQTT publish packet. |
| sim7020-write-cops | Sends "AT+COPS=" write command to SIM7020 module.
"AT+COPS=" command forces an attempt to select and register the GSM network operator. If the selected operator is not available, no other operator shall be selected. |
| sim7020-write-cpowd | Sends "AT+CPOWD=0" write command to SIM7020 module.
"AT+CPOWD=0" command forces the SIM module to switch off. |
